T&T: Tranny Oil Cooler

[Krogenguy]

Hmmm, interesting - our John Deere came w/ a fresh water cooled heat  
exchanger for the TD.  Could you switch to fresh water?  Operating  
temperature is in the low 200 range which the tranny seems to like.   
Just a thought.

Our Lugger engine came piped with a Bowman cooler on the raw water  
side for
the Twin Disc. This bronze cooler has no provision for zincs. Having
previously "lost" a non-zinc protected gear oil cooler to  
electrolysis on our
sailboat, I bought an inline zinc and installed it between the cooler  
and the
stainless exhaust spray ring. While wiring  it to the cooler, I   
wondered if this
improvement in protecting the cooler might be detrimental to  the  
spray ring
inlet fitting. Thoughts appreciated.
